Portfolio of the migration products

Early on Siemens recognized the significance of migration for process automation, and for many years has offered a wide range of innovative migration products and solutions for its glo- bally proven systems. Right from the beginning, the maxim of Siemens’ migration strategy is to modernize the existing in- stalled basis in steps without completely changing the system; and where possible without or with minimal plant downtime. Siemens has the products to support customers’ endeavors to achieve long-term safeguarding of investments together with maximization of their return on assets, even for legacy systems from other vendors.

Siemens’ know-how in the migration sector has continuously grown as time has passed. The experience gained in numerous migration projects has been incorporated into new products and technologies which are even more efficient. For example, "Data- base Automation" (DBA) is available for engineering of operation and monitoring systems. Using DBA and a plug-in interface, it is possible to download the configuration data, and to display and configure them using a standardized user interface. DBA allows system-based migration of operator system data from different output systems in standardized form, thus providing uniform software quality, security and understandability.

The migration products can be categorized as follows:
